The relevance of the application hydraulic thruster technology is determined by technological limitations drilling both vertical and horizontal wells. existing experimental studies confirm effectiveness technology, but its widespread implementation hindered lack scientific foundations for operation in combination with a downhole motor bit. Our research methodology includes methods analyzing tec...

Numerous observations accumulated principally during the last 40 years show that seismic waves generated from earthquakes and cultural noise may alter water and oil production. In some cases wave excitation may appreciably increase the mobility of fluids. The effect of elastic waves on the permeability of saturated rock has been confirmed in numerous laboratory experiments. Two related applicat...

The current work covers the evaluation of ultrasonic and electromagnetic (EM) techniques applied to temperature measurement and flow characterization for Enhanced Geothermal System (EGS). We have evaluated both ultrasonic techniques and microwave radiometry for temperature gradient and profile measurements. A waveguide-based ultrasonic probe was developed to measure the temperature gradient. A ...

A passive surface acoustic wave (SAW) pressure sensor was developed for real-time pressure monitoring in downhole application. The passive pressure sensor consists of a SAW resonator, which is attached to a circular metal diaphragm used as a pressure transducer. While the membrane deflects as a function of pressure applied, the frequency response changes due to the variation of the SAW propagat...

Downhole pressure is an important parameter for evaluating the production status of wells. A wireless monitoring system was designed downhole which consists two parts, i.e., tool and wellhead tool. The tubing used as information transmission medium between parts. includes four sensors, measured results will be applied to in form alternating voltage with a frequency 2.5 Hz. amplitude output by r...
